Schematic diagram of X-ray optics used in the study. Upstream left; b: beamstop and aluminium mask; c: cassette for imaging plate, which allows the use of the CCD camera behind when the plate is removed; i: image intensifier and CCD camera; p: pinholes made of 50 µm tantalum. The aperture sizes are 10, 20 and 50 µm from upstream. s: sample on a motorized x–z stage; v: vacuum path. Dimensions are in mm. |
